Measure when cooperating driver's grading operation now, generally be: earlier by measuring the worker in the place that will wipe off: preliminary survey-spade is scalped the soil of putting chi point superelevation-survey again-again shovel soil or pad soil, until this measuring point reaches designed elevation, puts the chi point with the albarium covering then.When motorized grader is wipeed operation off,, on the scope of operation of scraping, stayed the vestige of an irregular albarium just with this reference point as grading operation.Can't judge more than first this time of cutter deeply the driver of pilothouse, after first cutter was scraped, how many scope of operations also had apart from actual elevation, can't quantize.Cause the driver with sensation, high or low, blame in the measurement, measure for the second time even for the third time because also need.The driver also violates dimmed, because how many certain points scrapes on earth, the driver can't grasp, and often survey crew will be linked up for a long time with the driver, and survey crew must be held minute book and report the superelevation amount one by one to the driver in cab sometimes, and operation is extremely inconvenient.Also have thread-ligating therapy, bury the brick method and all can not address the above problem well.

Summary of the invention

The purpose of this utility model is to overcome the drawback that exists in the above-mentioned construction method, and a kind of superelevation indicator is provided, and emphasis solves the numerous and diverse and driver who measures on the operation and wipes the visual pattern problem of cutter depth data-measuring at present off.

The technical scheme that realizes the utility model purpose is a kind of superelevation indicator, it is characterized in that the isosceles triangle that the base equates with height that is shaped as of indicator bottom, leg-of-mutton high wide in indicator, leg-of-mutton drift angle

All indicate scale mark on two faces of indicator, wherein a scale mark " 0 " present position equals the thickness of indicator to the distance between the apex, and another side scale mark " 0 " present position is at leg-of-mutton top end.

Outside at indicator can also be equipped with outer cover, is provided with perforate on outer cover, so that the scale mark on two faces of indicator is exposed, in the following eaves design of outer cover foot-operated eaves is arranged.

Use indicator described in the utility model save time, save trouble, simply, conveniently, easy to operately, good understand, be subjected to survey crew and driver's favorable comment, make to measure to cooperate grading operation simple and clear, one-shot measurement, use the end, the cutter depth under the driver comes into plain view.Easily the superelevation data conversion is become the pictorial symbol on the scope of operation, present technique has reached changes complexity for simple, and changing measurement data is the purpose of pictorial symbol.

Specific embodiment

Make the method for superelevation indicator: get one of first-class hardwood plate (the most handy steel plate), be of a size of: 300*100*15mm, on plank, draw a center line AB, center line B looking somebody up and down from plank, on center line, get the size place of plank width, draw the wide line CD vertical together, connect BC and BD with center line, make it to form a base and the isosceles triangle that highly equates, the triangle tip angle is Under saw BC along the line and BD saw, with plane saw kerf is scraped, drawing accurate is the scale mark of unit from the plank tip B along center line with the millimeter, paints twice with varnish.Hold metal of making to emit at the A of plank and put, to prevent that hammer breaks plank in the use.The most handy metallic is done, and is durable in use, puts things right once and for all.Thickness of slab can be controlled in the 10mm when making of metal.

After the measurement of higher degree is finished, according to each measurement point superelevation data, indicator 1 is laterally squeezed into along the motorized grader working direction, on measurement point, the superelevation indicator of making 1 is vertically squeezed into the soil body equably with hammer, depth of drive=superelevation data+thickness of slab, after reaching absolute altitude, slowly indicator 1 is extracted, in the soil body sky that indicator 1 stays is had a rest, fill in and clear up sufficient albarium, root out unnecessary surface dust and lime out-of-bounds with the square iron shovel then, stay together " word " that albarium is clearly formed on the scope of operation, the length of " word " deducts the superelevation amount that the plate width is exactly this point.The motorized grader driver only need spread to little square with " word ", promptly arrives the absolute altitude position.Long and wide difference is timing, is superelevation (owing to scrape); When being zero, just in time on designed elevation; When negative, scrape for super.

When extracting indicator 1 can not about and rock back and forth, the most handy both feet slam the soil body of indicator 1 both sides, (when outer cover is arranged, can slam its down eaves) firmly slowly extracted and got final product.In order soil not to be taken out of, and the integrality that destruction soil body sky is had a rest, can also an outer cover 2 be installed in the outside of indicator 1, outer cover 2 front-backs are provided with perforate, so that the scale mark on the indicator 1 is exposed, in the design of the both sides of outer cover 2 foot-operated eaves 3 is arranged, when extracting indicator 1, slam foot-operated eaves 3 with both feet, slowly extract and get final product.
